He won’t in my opinion. Trump had the advantage in 2016 of being a political outsider which appealed to a lot of people. He won’t have the same support this go round. Whether it’s enough to have an effect remains to be seen. Biden won’t ignite the black vote the way Obama did, but he should still win that demographic handily.
No he won't. He can't put more than a couple hundred people together for a rally and then attacks the ones who show up and ask him tough questions. I'll disagree on your point of Trump won't have the same support. There are tons of people who didn't vote for him, me included, because we didn't really trust him or the system. However, since watching the administration who wouldn't transition, the media 24/7 attacks over lies and BS for 3 years, watching DNC leadership in Pelosi, Schiff, Nadler, Feinstein, the Green New Deal Party emerging, the Kavanaugh attack, the complete and utter disaster that was the Mueller investigation, the impeachment fiasco, record unemployment along all walks of life, the greatest economy boom in history, and the current unmasking of the Obama administration's treachery, that like me, there's many, many, many people who didn't vote in 2016 that will be out in force for him after what we've witnessed.
What I do predict will happen is Joe is pulled a couple months before the election and someone will be inserted with no expectation of having campaigned, rallied, or engaged ideas on a better way other than hate Trump, will run, and try to win on a mail-in vote scam. Sadly, there will be people who actually are able to overlook it all and let their TDS win out in the end.
